I ditto that. Keep it soaking in cold water, till you get the right product. Amazon.com should have the Shout Color Catcher sheets, and I've never heard of the othe rproduct, but I'm making a NOTE, right now - I saw your quilt on your blog, and IT IS GORGEOUS. Precision and all of that hand-quilting. The white/cream is so important, that I can't see dying the whole thing..........*maybe* cut pointy pieces and hand applique over the splotched ones? MORE work, I know, but you really put in so much work and it came out so fantastic, I just might do the appliquing.
